sssd and ding-libs (SL6)

The ding-libs packages contain a set of libraries used by the System
Security Services Daemon (SSSD) as well as other projects, and provide
functions to manipulate file system path names (libpath_utils), a hash
table to manage storage and access time properties (libdhash), a data type
to collect data in a hierarchical structure (libcollection), a dynamically
growing, reference-counted array (libref_array), and a library to process
configuration files in initialization format (INI) into a library
collection data structure (libini_config).
